Neither Michael Jackson or Debbie Rowe are the biological parents of the oldest two children. Apparently they were conceived in vitro (which means outside the womb.) Multiple sources say that Michael was also not the sperm donor for any of his kids nor was Debbie's eggs used. She was just the surrogate, and paid for doing so. The actual biological parents were never told of the identity of the "receiving parent" who turned out to be Michael Jackson. It is also being reported that Michael never legally or formally adopted his 3 children.
